  • • Failure to comply with WHS Act 2011 and associated regulations, codes of practice and Australian Standards for machinery and lasers
  • • Inadequate consultation with workers, HSRs and contractors about laser cutter risks and changes to systems of work
  • • Absence of formal WHS objectives and performance indicators for CNC laser cutter operations
  • • Poor integration of laser cutter risks into the organisation’s overall WHS management system and risk register
2. Procurement, Design and Specification of CNC CO2 Laser Cutter
  • • Selection of a laser cutter that lacks adequate built-in guarding, interlocks or safety functions for Australian workplace conditions
  • • Imported equipment that does not comply with Australian Standards, electrical requirements or laser safety classifications
  • • Inadequate specification of extraction and filtration capacity for fumes, smoke and particulates generated by CO2 laser cutting
  • • Failure to specify appropriate emergency stop, isolation and lockout capabilities at design/procurement stage
  • • Lack of compatibility between the laser cutter control systems, software and existing organisational IT and safety systems
3. Installation, Workshop Layout and Environmental Controls
  • • Poor workshop layout leading to restricted access to emergency stops, isolators or exits during an incident
  • • Inadequate ventilation or fume extraction causing accumulation of hazardous fumes, smoke or odours from laser cutting
  • • Incorrect electrical installation or overloading of circuits creating fire and electric shock risks
  • • Incompatible location near flammable materials, incompatible processes or foot traffic routes increasing likelihood and consequences of incidents
  • • Insufficient lighting, noise control or visibility around the laser cutter affecting supervision and safe operation
  • • Inadequate segregation between the laser cutter and other work areas, exposing bystanders to emitted radiation or ejected fragments from catastrophic failure
4. Laser Safety Management and Radiation Control
  • • Exposure to hazardous laser radiation (direct beam, reflections or scattered radiation) due to inadequate enclosure integrity or interlock failures
  • • Defeating or bypassing interlocks, guards or safety switches for convenience or maintenance tasks
  • • Lack of formal classification and documentation of the laser system and associated control measures
  • • Inappropriate or non-compliant laser protective eyewear and inadequate labelling of laser hazards
  • • Poor management of software or firmware changes that may affect laser safety functions or limit settings
  • • Absence of clear access control to the laser cutter area, allowing untrained persons or visitors to be exposed to laser risks
5. Fume, Smoke and Airborne Contaminant Management
  • • Generation of hazardous fumes, gases and particulates from cutting, engraving or marking various materials (e.g. plastics, timber, composites)
  • • Inadequate assessment of materials being cut, leading to unintended release of toxic or corrosive substances
  • • Poorly maintained extraction and filtration systems resulting in reduced performance and build-up of contaminants
  • • Uncontrolled discharge of fumes to the external environment causing environmental or public exposure issues
  • • Failure to monitor and manage worker exposure to airborne contaminants over time
6. Fire, Explosion and Thermal Risk Management
  • • Ignition of combustible materials (workpieces, residues, extraction filters) within the laser cutter enclosure or ducting
  • • Accumulation of flammable dusts or offcuts in the work area, extraction system or filters increasing fire load
  • • Inadequate selection or placement of fire extinguishers and inappropriate response procedures for laser-related fires
  • • Overheating of mechanical or electrical components due to inadequate maintenance or cooling
  • • Uncontrolled use of materials with flammable substrates, coatings or laminates in the laser cutter
